Abstract
The utility model discloses a structure facilitating long rails to move along rail grooves, in which a plurality of roller assemblies are arranged at intervals on rail grooves at the left side and the right side of a plurality of sleepers arranged side by side, each roller assembly comprises a roller seat fixed at the front side of the rail groove and a roller arranged on the roller seat through a roller shaft, and a bearing is arranged between the roller and the roller shaft. When a long rail is paved, the end part of the long rail is clamped by a traction device, the bottom of the long rail is arranged on the roller of the rail groove, and when the long rail is pulled by the traction device to advance, the roller is driven by the long rail to rotate. The long rail and the roller on the rail groove are in rolling friction, and the friction force is far less than sliding friction. So the traction force of the traction device pulling the long rail to advance can be smaller, and the power consumption of the traction device is low. The friction force between the long rail and the roller is small, the abrasion of the long rail and the rail groove can be reduced, and the sleeper can not move and overturn accordingly, which is conductive to improving the installation efficiency of the rail.
Description
Technical field
The utility model relates in the track laying process, the structure that long rail moves along the rail groove.
Background technology
The rail of high-speed railway, in order to guarantee the comfortableness of train driving, rail need adopt continuous welded rail track, and common long rail by 500 meters long is welded.In the process of deployment, long rail is by the draw-gear clamping, drag it along sliding in the rail groove of the sleeper that is arranged side by side by the draw-gear holder, the length of long rail is very long, and weight is very big, needs very big tractive force when holder is dragged it and moved, and long rail length is very long, therefore in the process of deployment, the distance that need drag is very long, and to drag the process power consumption very big in whole holder.Simultaneously, holder is dragged in the process, and long rail directly contacts with the rail groove, and holder is dragged in the process, and heavy long rail and interorbital frictional force are very big, and the holder of long distance is dragged in the process, and long rail and rail groove are worn easily.In addition, frictional force is big, pulls in the process, and the active force that sleeper is subjected to long rail is bigger, and sleeper is followed the danger of moving and turning on one's side in addition, has a strong impact on the installation effectiveness of track.
Summary of the invention
Of the present utility modelly be intended to provide a kind of structure that long rail moves along the rail groove of being convenient to, so as can be with the moving long rail of less tractive force holder, reduce the wearing and tearing of long rail and rail groove, the installation effectiveness of the long rail of raising.
Described in the utility modelly be convenient to the structure that long rail moves along the rail groove, on the rail groove of the plurality of sleepers left and right sides that it is arranged side by side at interval drum assembly is installed, described drum assembly comprises the roller seat that is fixed in rail groove front side and is installed on cylinder on the roller seat by the tube axle, between cylinder and the tube axle bearing is installed.
Described in the utility modelly be convenient to long rail along the structure that the rail groove moves, be arranged at intervals with drum assembly on the sleeper that is arranged side by side, the cylinder of drum assembly is rotatable.When laying long rail, the long rail of draw-gear clamping, long rail is placed on the interior cylinder of rail groove, when draw-gear pulled long rail, long rail drove the cylinder rotation, is rolling friction between long rail and cylinder, its frictional force is much smaller than sliding friction, draw-gear can spur long rail by less power and advance, and its power consumption is less, energy-saving and environmental protection.Simultaneously, frictional force is little between long rail and cylinder, also can reduce the wearing and tearing of long rail in the installation process, rail groove, cylinder greatly.In addition, frictional force is little, and is less to the active force of sleeper in the long rail moving process, and sleeper can not followed and be moved and rollover, thereby help improving the installation effectiveness of track.

Fig. 1 is a structural representation of the present utility model;
The scheme of installation of Fig. 2 drum assembly;
Fig. 3 is the lateral view of Fig. 2;
Fig. 4 is the vertical view of Fig. 2.
The specific embodiment
As Fig. 1, a kind ofly be convenient to the structure that long rail moves along the rail groove, its on the rail groove 2 of plurality of sleepers 1 left and right sides that is arranged side by side at interval drum assembly 3 is installed, described drum assembly 3 comprises roller seat 31, roller seat is fixed on the sleeper 1 by locking devices such as screws, the two ends of tube axle 32 place on the roller seat 31, and the tube outer shaft sleeve has cylinder 33, and cylinder is equipped with bearing 34 with the tube between centers.
The two ends of tube axle 32 can be fixedly mounted on the roller seat 31, as Fig. 2, Fig. 3, there is U type seat 35 both sides of roller seat 31, tube axle two ends place respectively on the U type seat, the upside of tube axle is provided with the breach 37 of truncation, cover plate 36 places on the breach with U type seat both sides and fastens, and fixes by securing member such as screw and U type seat, and tube axle two ends are fixed on the U type seat.
During long rail laying, its end is by the draw-gear clamping, and the bottom places on the cylinder of rail groove, and when the long rail of draw-gear pulling advanced, long rail drove cylinder and rotates.Be rolling friction between the cylinder on its long rail and the rail groove, frictional force is far smaller than sliding friction.Therefore, the tractive force that the long rail of draw-gear pulling moves ahead can be less, and draw-gear is low in energy consumption.Frictional force is little between long rail and cylinder, also can reduce the wearing and tearing of long rail and rail groove, and sleeper can not followed yet and be moved and rollover, helps improving the installation effectiveness of track.
Claims (1)
1. be convenient to the structure that long rail moves along the rail groove for one kind, it is characterized in that: on the rail groove of the plurality of sleepers left and right sides that is arranged side by side at interval drum assembly is installed, described drum assembly comprises the roller seat that is fixed in rail groove front side and is installed on cylinder on the roller seat by the tube axle, between cylinder and the tube axle bearing is installed.
